- 2 tablespoons extra-virgin olive oil, or as needed
- 8 large skinless, boneless chicken thighs
- 1/2 Spanish sweet onion, chopped
- 4 cloves garlic, crushed
- 1/2 cup rice wine vinegar
- 1/4 cup soy sauce
- 2 tablespoons ground cumin
- 2 bay leaves
- 2 tablespoons tomato paste
- 2 tablespoons chipotle sauce
- 1 1/2 tablespoons arrowroot powder, or as desired
- 1 (16 ounce) package dry flat rice noodles
- Heat olive oil in a large pot over medium heat. Cook chicken thighs in hot oil until no longer pink on the outside, 1 to 2 minutes per side. Add onion and continue to cook until the onion is translucent, 5 to 7 minutes. Stir garlic into the chicken mixture; cook and stir until fragrant, about 1 minute. Add vinegar, soy sauce, cumin, and bay leaves to the pot. Stir tomato paste and chipotle paste into the liquid in the pot.
- Bring the mixture to a simmer and cook until the chicken is no longer pink in the center and the juices run clear, about 20 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Stir arrowroot powder into the liquid at the bottom of the pot; continue cooking until the liquid thickens, about 5 minutes.
- Bring a large pot of lightly salted water to a boil. Cook rice noodles in the boiling water, stirring occasionally, until cooked through but firm to the bite, about 4 minutes; drain. Ladle sauce and chicken over the noodles to serve.
